    AMP head rated 600W @ 4 ohms
    900W @ 2 ohms.
    switch to engage 2 ohm load

    have a 2x10 cab rated 400W @ 4 ohms
    and a 1 x 15 rated 400W @ 8 ohms

    If I paid attention in math class - using both cabs will be 2.66 ohms & 800W

    So I assume the 2.66 ohm with AMP set to 2 ohm will not damage the AMP.
    The ".66" ohms will prevent the AMP from putting out the full 900W, so drivers should be save.

    Is this sound math? will the 2.66 load and 2 Ohm setting cause any weird distorted tones?

    You'll be safe as far as ohms goes but you'll have enough power to damage either cabinet.

    Also: specifics matter so asking these questions works better if you say which amplifier and which cabinet.

  3. ^ manufacturer here can make a big difference. No "general" answers for cabs or heads for that matter.
